In the article titled “A Randomized Trial of a Low-Carbohydrate Diet vs Orlistat Plus a Low-Fat Diet for Weight Loss,” published in the January 25, 2010, issue of the Archives of Internal Medicine (2010;170[2]:136-145. doi:10.1001/archinternmed.2009.492), an error occurred in Figure 2 on page 143, where the lines of the graph were mislabeled in the key. The solid line should be for “O + LFD” (orlistat plus a low-fat, reduced-calorie diet), and the dashed line should be for “LCKD” (low-carbohydrate, ketogenic diet).
